Write File.vi does not allow for offset entry

[MikeW]

I am using a Write File.vi to write data to my hard drive like always but I have never used the offset before and it is not allowing me to enter an offset value and the error message does not make sense. The error says you have wired different data types but then say source long, sink long which are the same in my eyes.

Is there a trick to using the offset?

If you are writing to file different data types, the use of input is not allowed because it depends on the number of bytes used to store the type (that's why it should be just one type)
